Hitler's biggest mistake

Answer 1

first answer:

Betraying Joseph Stalin and invading Russia, even after Hitler promised Germany would not fight Russia.

My answer:

I disagree. Hitler's primary goal before the war was the defeat of Stalin's Soviet Union to end the threat of communism in Germany & Europe. Hitler falsely assumed that for him to attack the Soviet Union he would have to first defeat France, so he wouldn't have to worry about an attack from France during a war with the USSR. This assumption was based on the history of prior-alliances between France & Russia.

But times and situations had changed for France & Russia. Russia was now a communist nation. In reality, Stalin was hated & feared throughout all of Europe. The Soviet Union had no friends or allies. If Hitler had attacked the USSR first, no other nation would have helped the USSR. Several nations would have and did help Germany attack the Soviet Union: Finland, Romania, Hungary, Bulgaria. Maybe even Poland would have helped.

Poland sat between Germany & the USSR. Hitler assumed he would have to seize Poland before he could invade the USSR. Was it really necessary?

When Japan joined the Axis (Germany & Italy) in 1940, Hitler should have gotten a commitment from Japan to help Hitler defeat Stalin. But he didn't, instead the Japanese would later attack the USA, giving Hitler a reason to Declare War on the US. This just made things worse for Hitler & Japan.

Hitler's biggest mistake in my opinion was not finding a way to defeat the Soviet Union without involving the French, British, and the United States in the war.
